COMPRESSION STOP AND WASTE COOK.

Specification of Letteris Patent.

Patented Feb. 2, 1900.

Application flied June 13, 190']. Serial No. 378,848.

Toall whom it may concern.-

Be it known that I, ROBERT W. BEATON,

citizen of, the, United States of America,

liquid and draining that portion of the pipe cut off from the main water supply.

To this end, I have devised a novel valve wherein positive and reliable means are emloyed for closing the valve and openin rain ports, whereby the back pressure water in a pi e can e relieved. The valve is especially esigned for water mains, where it is desired to drain the mains or their outlet pipesand prevent the same from bursting,

by water freezing in the mains or pi es.

The detailed construction of t e compression stop and waste cock will be presently described and then specifically pointed out in the appended claims.

Referring to the drawing forming art of this specification, like numerals of re erence designate corresponding parts throughout the several views, in which,

Figure 1 is a vertical sectional view of the valve. Fig. 2 is a horizontal? sectional view taken on the line zm of Fig. i. Fig. 3 is an elevation of a port valve, and Fig. 4 is a perspective view of a portion of the valve cas- Io put my invention into practice, I provide an inverted T-shaped ody or valve casin having a water inlet 2, and an outlet 3. file valve body is provided with a transverse partition 4 having a horizontal ortion 5 beneath the bonnet 6 of the valve bo ,said horizontal portion being provided with an opening 7 surrounded by a valve seat 8.

The bonnet 6 is formed with a horizontal partition 9 formed with a central rectangular opening 10 and with a plurality of o enings 11. T e bonnet is formed with a p urality of drain ports 12, each ort having a seat 14. These drain ports-as be seen by reference to Fig. 4 are substantiall L-shape in form, the horizontal portions 9 the ports openin at the exterior of the bonnet and the vertica portions thereof being have been thoroughl within bosses formed integral with the wa s of the bonnet and with the partition 9, the upper ends of said bosses forming seats 14. estin upon the seats 14 of the ports 12 is a gasxet 15carriedby a ort valve 16', said valve having a rectangu ar boss or nut 17 projecting into the operung 10 of the partition 9. The boss or nut 17 is interiorl threaded, as at 18, to receive a threaded e argernent 19 carried by a valve stein 20. The lower end of the valve stem 20 is provided with a beveled head 21 upon which is secured a valve, embodying a metallic member 22 and a gasket 23, said member 22 and gasket 23 being secured to the head 21 by a screw 24. The member 22 is preferably made of malleable metal and is bent'to en age the head 21, whereby it can be revolve upon said head.

The upper end of the valve stem 20 passes through a depending sleeve 25, seating in the top of the bonnet 6 and retained therein by a gasket 26 and a cap 27 threaded upon the upper end of the bonnet 6. The sleeve serves functionally to guide the s ring 30 in its corn ression, also to limit t e upward movement of the port valve 16. The stem 20 passes through a conventional form of stufllug-box 28,-.carried by the ca 27 and is provi ed with a. handle 29. e stem 20 directly beneath the cap 27 is provided with a collar 27 for limiting the upward movement of the stem 20, preventing said stem from being screwed from the port valve 16, unless the cap 27 is removed.

Surrounding the sleeve 25 and bearing upon the port valve 16 is a coiled s ring 30 employed for normally holding the port valve 16 upon the seats 14 of the ports 12.

When water or similar liquid is passing through the valve body, the valve stem 20 is elevated, as illustrated in Fig. 1 of the drawings. To shut off a suppl of water, the valve stem 20 is rotated unti the gasket 23 engages the seat 8 of the partition 5, and upon further rotation of the stem 20, the sort valve 16 is elevated, allowing water to rain through the ports 12, until practically all the pipes connectin with the opening 3 rained of water.

The gasket 23 frictionally engaging the seat 8, allows the head 21 to revolve in the valve 22. During such revolution of the head 21, the screw 24 is carried therewith, the shank of the screw at the oint Where the latter is engaged by the va ve 22 and the gasket 23 being free from threads, so that the screw may be readily revolved in said valve and gasket. In openin the valve, the port valve 16 is first seated efore the asket 23, valve 22 and valve stem can be e evated.

It is thought the construction and operation of the valve will be fully understood from the foregoin description taken in connection with the drawings, and I reserve the right to make such structural changes as are permissible by the appended claims.

Havin fully described my invention, what I c aim and desire to secure by Letters Patent is:

1. A valve consisting of a body having an inlet and an outlet opening, a bonnet carried by said body, a partition arranged in said body and having an o ening formed therein, a horizontally dlspose partition arranged in said bonnet, said partition having a plurality of openings formed therein drain ports formed in said bonnet, a port valve mounted in one of said 0 enin sin the partition in said bonnet and adaptef to normally close said drain ports, a valve stem threaded in said port valve and having a head, a revoluble valve carried by said head for closing the opening in the first mentioned partition, a depending sleeve mounted in said bonnet, a spring surrounding said sleeve and bearing upon said port va ve, and a cap carried by said bonnet for guiding the movement of said valve stem 2. The combination of a valve body, a partition arranged in said body and rovided with an opening, a bonnet carrie by said bod a partition arranged in said bonnet and aving a central 0 ening and a plurality OfOPBIllIlgS arrange around the central opening, a uralit of drain ports in said bonnet, the walls of which extend upwardly Within the bonnet and form seats, a ort valve normally engagin said seats and aving a depending interior -threaded nut projecting into the central opening in said bonnet partition, a valve stem threaded. into said nut, a valve revolubly mounted on the lower end of said stem for closing the opening in the valve body partition, a cap earned by said bonnet for guiding the movement of said stem, and a spring arran ed within said bonnet and bearing upon sai port valve for holding the valve during a period of rotation of said valve stem.

3. In a valve, the combination with. a body having a partition formed therein rovidefi with an opening, of a bonnet carried. by sai body, a partitlon arranged in said bonnet havin a central openin and also having ports Tormed therein, sai bonnet having a plurality of drain ports formed therein, a valve stem extendmg through the central opening of said partition, a valve carried by said stem for closing the first mentioned opening, means surrounding said stem and moved thereby for closing the drain orts in said bonnet, and. means for holdin t e first mentioned means during a perio of rotation of said valve stem.

4. The combination with a valve casing having a partition between the inlet and outlet of the casing, said partition having an opening and a valve seat surrounding the opening, of a bonnet carried by the valve casing and provided at its lower end with a partition provided with a central opening and a plurality of openings around the central opening, a plurality of bosses integral with the bonnet and said bonnet partition and projecting upwardly from the partition, drain ports extending through said bosses and bonnet, a port valve seatin on the upper ends of said bosses and norma y closing the drain ports and havin a nut engaging the centra opening in sai bonnet partition, a valve stem havin a threaded portion engaging said nut, a valve on the lower end. of said stem for engaging the valve seat carried by the first mentloned partition, and means in the bonnet engaging the port valve for normally holding the same seated to close the drain ports.

In testimony whereof I aflix my signature in the presence of two witnesses.

ROBERT W. BEATON.
